Nope it's only one week of data starting from: 27-04-2018 - 04-05-2018.
Since that was the time @dimimp, started to give out delegations.

The plan is to do this weekly with data from the previous week. Oh and thanks!

Also the reason why the data is 1week late is to make sure that payout is really done. Some people in here might "unvote" someone, or the post being upvoted might be flagged by someone, thus to make sure that the data is almost accurate, we check after the payout is done which is after a week. Hope this makes sense :)
